My invention relates to a sleeve pressing machine for laundries, which is particularly adapted for pressing the sleeves of laundered shirts.

An object of the invention is to provide means for automatically holding sleeves of different sizes against a buck for pressing, and to provide such means in yielding form.

Still other objects are to provide a rotary buck upon which sleeves can be pressed and to provide means for peeling the shirt sleeves from the buck after pressing, during the rotation thereof.

A further object is to provide mechanism in such a pressing machine to prevent the cuff of the shirt from becoming twisted during the pressing operation, and as an exemplification of such object, to provide a separately rotatable cuff support which follows rotation of the rotary buck but is capable of independent rotation, to avoid twisting of the cuif.

A still further object is to provide a generally upright, rotary mandrel for pressing a shirt sleeve, to facilitate drawing a sleeve thereon and removing a sleeve therefrom, in combination with a rotating pan for supporting the rest of the shirt while the sleeve is being pressed.

My invention also has for its objects to provide such means that are positive in operation, convenient in use, easily installed in a working position and easily disconnected therefrom, economical of manufacture, relatively simple, and of general superiority and serviceability.

The invention also comprises novel details of construction and novel combinations and arrangements of parts, which will more fully appear in the course of the following description. However, the drawings merely show and the following description merely describes embodiments of the present invention, which are given by way of illustration or example only.

Referring more in detail to the drawings, reference numbers indicate side plates of my pressing machine, which pivotally support a generally upright lever 3|, which is shown pivoted on the side plates at 32. The lever 3| carries a pressing head 33 which has a concave face 34 shaped to fit the side of a truncated cone. The pressing head is mounted on the lever 3| by means of an arm 35 projecting rearward from the head 33, which arm is pivotally connected to a clevis 36 bolted within the lever 3|, as shown at 31. The belt 31 is free to slide in an aperture in the lever 3| but a spring 38 coiled around the shank of the bolt 31 tends to hold the head 33 yieldingly upon the lever. A pin 39 fastens the arm 35 within the clevis 36.

The head 33 also has a rearwardly projecting lug 40 to which is pivoted another lever 4|. The two levers 3| and 4| are pivotally connected to each other by a pin and slot arrangement shown at 42 and 43, in order to compound same. The lever 4| is fulcrumed at 44 on the frame of the machine. A pin and slot arrangement 45 and 46 is also provided by the lug 40 and the adjacent arm of the lever 4|.

The compound leverage of the two levers 3| and 4| is arranged to advance the pressing head 33 forward to a pressing position at the proper angle.

Spring means 41 tends to move the head 33 away from a pressing position by reason of a connection of the spring with the pivot mounting the toggle is at least partially straightened out,

as shown in broken lines in Fig. 2.

The cylinder 53 has a ball and socket con? nection 5'! with a platform 58 mounted between the side plates 30, whereby the cylinder 53 may follow the swinging movements of the toggle links. An inlet fitting 59 supplies pressure, fiuid, such as compressed air, to the cylinder 53, from a source (not shown). c

A table 60, disposed upon the side plates 30 and bridging the space therebetween, supports a rotating pan BI. Spaced annuli 62 and 63 rotatably support the pan 6| about a rotating column 84. It is believed clear without further illustration that the pan I5I may be fastened to the upper annulus 62 by any suitable means, and that the annuli may be fastened together and spaced apart by suitable tie and spacer means.

A toothed ring 65 is'arranged between the annuli 62 and 63, the teeth being shown at 66. The ring 65 is mounted upon the column 64. The pins 61 are disposed in pairs between and arranged around the inner opening provided by the annuli. It will be noted that the column 64 is eccentric with regard to the annuli 82, 63 for a purpose hereinafter described.

Rollers 68 ride between the annuli G2 63 to rotatably support the pan 6|. Eccentric bolts 69 support the rollers upon the table-60. The eccentric arrangement permits in-and-out adjustment of the rollers lit-with respect to the periphery of the annuli.

As the toothed ring 65 rotates, its teeth engage the pins 9'! as suggested. in Fig. 12, and effect conjoint rotation of the pan GI and column 64.

Mechanism to rotatethe column 64 comprises a ring gear I that. is engaged and driven bya reciprocating rack II. A pivoted dogIZ on the ring gear I0 interlocks with a crown gear. I3 when the ring gear I0 is rotated in one direction, and idly slides. along the crown. gear when the ring. gear is rotated in the opposite direction, whereby to drive the column in one direction .by reciprocation of the rack. The-crown gearv I3 is pinned to the column 64. as suggested at I4 in Fig. 16.

A fixed housing I5, around which the column 64 rotates, is mounted upon the table 69 by flange means I6. Integral with the housing I and arranged thereon is a steam chest 'I'! in the shape of a truncatedcone. A partition 78 divides the interior of the housing I5 from the interior of the steam chest 11. A steam pipe I9 extends through the housing I5 and, empties into the steam chest 11, while the pipe 80 discharges the products of condensation from the steam chest. A bushing 8I extends through the steam chest IT for housing a reciprocating rod 82. The bushing 8| is in steam-tight connection with the chest I? and stationary therewith.

Mounted to rotate around the steam chest is a mandrel 83 that is fastened upon the rotating column 64. Suitable padding 84 is applied to the mandrel 83 and a fabric covering 85 is placed upon the padding. The mandrel 83 is supported 4 upon ball bearings 86 in races between inwardly directed flanges 8'! and 88 at the topof the mandrel and the steam chest, respectively.

Independently rotatable upon the top of the mandrel 83 is a cuff support 89. It will be noted in Fig. 7 that there is no positive connection between the cuff support and the mandrel top flange 81. There is some friction between those parts which restricts the independent rotation of the cuff support 89. Howeven'the cuff support is sufliciently rotatable independently to prevent the cuff of a shirt sleeve from being twisted with respect to the rest of the sleeve.

Clamp means are provided for holding a cuff against the knurled portion 90 on the cuff support 89. The'clamp means comprises clamping ,members, QI arranged to clamp a cuff 94 in place on the support 89.

"The members 9I are mounted upon bell cranks 93 that are pivoted on shafts 92 mounted inside the cuff support 89.

The reciprocating rod 82 carries thereon a combination. abutment 95, and lug 96. A coil spring 91 abuts against the abutment 95 and the floor 98 of the cuff support, tending to raise the rod 82; The reactive force of spring 91 also effects frictional engagement of said cuff support and. mandrel. 8-3. Links 99 pivotally connect the lug 96 with the bell cranks 93, so that when the rod 82 is raised by the spring, the clamp members 9i swing to. cufi clamping positions.

Operating means, for moving the. rod 82 downwardly against the action of the spring 9'! comprises a. bar I00 having a hooked end IOI that engages the rod 82. The, bar I00 is connected with a lever I02 which is fulcrumed on a shaft I03 between the side plates 30 of the machine. An adjustable link I04 connects the lever I02 with another lever I05, which in turn is fulcrumed on. the shaft I06 also between the side plates 30. The lever I has a reduced end I0! that projects through anopening in a pivoted bar I08, at thefront; of the machine. The coil spring I09 connects the projecting end I0! with a relatively fixed bolt H0 ona front plate III that is supported on the table 60. The spring I09. tends to assist the spring 91 through said system of, leverage. The assistance is rather in nature of spring I09 supporting the weight of said system of levers so that said weight normally cannot act to depressrod 82 against the lifting force'o f spring 91. A pedal I I2 pivoted at I I3 near the rear of the machine, is mounted ona bar to depress both springs when an operator steps on the pedal and thereby raise cuff clamps 9|. v

The pressing head 33 contains a steam chamber II4. Bracing wall II5, shown in Figs. 5 and 6, may be employed for strengthening same. Passages II6 through the wall H5'connect the halves of the chamber II4 with each other, Pipes II! and H8. supply steam to the chamber portions I I 4 at the lower ends thereof. Steam fitting means II9-are shown connected to the pipe. II'I onvone sidejof thepressing head 33'. One end of a flexible conduit I20 is connected to a steam .fitting H9, and the other end of said conduit-isconnected to a steam fitting I2 I, that is providedrwith a pipe I22 onto which is fitted a flexible conduit,.not shown, which leads to and connects with the pipe IIB on the other side of the pressing head. 1

.r Actuating'means fortherack II consists of a lever I23 pivoted on a side plate 30, at I24. The lever 'I 23 .is c'onnected atone end with a clevis I projecting from the end of the rack II, and the other end of the lever is bifurcated as shown at I28, to straddle a pin I21 carryin spaced c01- lars I28. The inner end of the pin I2! is threaded to receive nuts I29 for locking the pin on the main lever 3|. Thus swinging movement of the lever 3I will cause the smaller operating lever I23 to swing from the full line position to the broken line position in Fig. 14, about the fixed point I24. This swinging movement of the lever I23 is transmitted into reciprocating movement of the rack II. The clevis I25 is screwed upon a bar I that in turn has a clevis connection I3I with the rack II. This arrangement permits a slight upward and downward oscillation of the bar I30 necessary to accommodate the swinging movements of the lever I23.

A stationary collar I33 is arranged around the column 84, within the pan BI. The collar is bolted to a lower portion of a relatively station ary stripper or peeling plate I34, which strips or peels the sleeve from the rotating buck after pressing. The stationary plate I34 extends down inside the collar I33 and has a foot I35 that is bolted to a flange I6 at the bottom of the housing 45, by means of one of the bolts 69, as perhaps best shown in Fig. '7. The leading edge of the stripper or peeling plate I34 is arranged in close proximity to the rotating buck 85 to facilitate this stripping or peeling action.

Sleeve distending means are provided at one side of the pressing buck in order to effectively smooth the sleeve at the opposite side of the buck, opposite the pressing head. Pivotally connected on a pin I38 at the top of the stripper or peeling plate I34 is a wire I 31 that extends into and is suitably connected to one end of a coil spring E38 by any suitable means, such as by welding.

A bar or tubular member I39 has endwise projecting pins suitably fastened in the opposite end of the spring I38 and to an end of a spring I49, respectively. The other end of the spring I 40 is similarly fastened to a rod I4I pivoted 'at I42 to a pull bar I43. The pull bar I43 is in turn.

pivotally connected with an arm I44 adiustably connected to the lever I82 and actuated by the pedal I I2 in the same manner as the bar I88 hereinbefore described.

The springs I38 and I40 normally tend to swingthe sleeve distender outward from the buck 85 so that a sleeve thereon is smoothed out on the opposite side of the buck from the distender.

In the operation of my present sleeve press, a sleeve is passed over the sleevebuck 85 and the remainder of the shirt laid in the pan BI. The pan 8| rotates with the buck to prevent twisting of the shirt sleeve on the shirt.

The operator steps on the pedal II2, which draws the extender member I39 toward the buck 85 and simultaneously moves the cuif clamps away from the culf mandrel 89. The shirt sleeve may then be drawn down over the buck 85, over the extender member, and over the cuff mandrel. When the end has been smoothed out around its mandrel 89, the pedal I 12 may be released, which causes the spring 91 to urge the clamp 9i to clamping positions with respect to the cuff 94. Releasing the pedal I I2 also causes the extender,

under influence of the spring I 09, to push the sleeve outward away from the buck on the side opposite the pressing side. The springs I38 and I48 tend to smooth the shirt sleeve on the pressing side, opposite the pressing head 33, after the pedal I I2 has been released.

It is believed clear that while the cult mandrel 89 substantially follows rotary movements of the buck due to the friction of their abutting faces, there is no positive connection that compels this conjunctive movement. For this reason any tendency of the cuff to become twisted upon the sleeve is counteracted, for the tendency of the cuff to so twist will cause the mandrel 89 to slip with respect to the buck 85, until the tendency to twist is overcome. It will be noticed that there is a rotary or swivel connection between the rod 82 and the hooked end IIlI to permit rotation of the rod 82 with the cuff mandrel 89.

The springs I38, I48 have the further distinct advantage of fittin large sleeves or small ones, thus readily adapting the present press to different sizes of shirts. Moreover these springs provide rounded corners in the sleeve.

It is believed clear without further illustration that any suitable means, manual or pedal, may be employed for controlling the prime mover 53 and the pressure fluid for operating it. Suitable means are shown in United States Letters Patent No. 2,332,830, issued October 26, 1943, to Otto H. Pearson.

Sufiice to say, when the pressure fluid is admitted to the cylinder 53 to actuate the piston 54 therein, the piston rod moves the toggle links 58 and 5| towards a straightened relationship, such as the broken line position in Fig. 2. This movement swings the lever 3! about its pivot, as also indicated by broken lines in said Fig. 2. The pressing head 33 is thereby bodily moved forward to a position of engagement with a shirt sleeve on the buck 85, as also indicated in broken lines in Fig. 2. The compound action of the levers 3| and 4! moves the pressing head 33 forward to a position substantially parallel with the buck. This action aids in moving the lower end as well as the upper end of the head 33 away from the buck between pressing operations. so that the pressed shirt may be removed and a new one placed on the buck.

Due to the mechanism perhaps best shown in Figs. 13 to 16, each time the pressing head is moved rearward away from the buck 85, the rack II rotates the buck 85, automatically thus presenting a diiferent portion of the sleeve to the pressing head for the next pressing operation. Moreover as the buck rotates, the relatively stationary plate I34 acts as a peeler or stripper to remove the pressed portion of the shirt sleeve from the buck since there is a tendency for the pressed portion of the sleeve to stick on the buck after pressing. This peeling or stripping is done automatically by rotation of the buck. The pan 6 I, as stated, rotates with the buck 85. It is believed clear that the relatively large springs 41 return the pressing head 33 to its inoperative position when the press is released from the piston 54. During pressing, the pressing head 33 is self-adjusted to the buck by means of the pivotal connection 39 and the spring 38. This is of distinct advantage, since there may be unevenness in the padding on the buck and then, of course, there is a diiferent relationship between the head and buck when the padding is first applied to the buck and after it has become matted down. This is compensated for by said means.

It will be noted, especially in Fig. 12, that the vertical axis of the buck is eccentric with respect to the vertical axis of the driving plate 63. This is necessitated by the fact that the stationary peeler or stripper plate I34 extends up through amazes:

the rotating pan 6| and it is desired to-have a minimum of spacebetween the rotating'pan' and adjacent the stationary peeler through which parts of the shirt being pressed can .get intothe working mechanism.

While I'have illustrated and described what' I now regard as the preferred embodiments of my invention, the constructions are, of course, subject to modifications without departing from the spirit and scope of my invention.
